Albino trees exist in nature, but they’re rare. These trees contain a gene mutation that causes them to lack chlorophyll, so their leaves are white. In California, albino redwood trees are parasites. They survive off the energy from nearby redwood trees. Why do you think they need to use energy from other trees to survive?

They need to use energy from other tress to survive so that they can do basic functions, like absorbing nutrients from the ground, and growing back leaves. They don't have chlorophyll, so they need that energy to do the functions I mentioned above.

Explanation: Hope this helps!

Trees need chlorophyll to make energy. Because albino trees don’t have chlorophyll, they can’t create their own energy. So, they must take energy from other trees to survive.

Explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
